Do any of you use amazon mechanical mturk?

I recently joined a amazon affiliate program called amazon mechanical mturk, someone here told me about it, and so far it very interesting all you have to do is complete a human intelligence task called hit most of the hits are pretty easy but some of them are a little harder but so far it seems to be a pretty good program for those who want to earn a little extra money. are any of you a member of amazon macanical mturk?

I joined it about two to three weeks ago. I am now at 17 dollars. I just get on there as often as I can and complete as much as I can. I try to stick to the easy ones. Even they some only pay one to five cent it adds up if you do alot.
